I watched 9 last night. While the plot is a bit simplistic, visually it is absolutely stunning. I think I was more into the steampunk parts in it, the mixture of old with new. The gearing and stuff was really cool.
The movie does read like a manic depressives manifesto, but for it's short running time it is certainly worth the rental.
Recommended. Probably pretty scary on acid.
